ABSTRACT:
A television system (TV) with an interlaced display screen for displaying network application data. A flicker filter is preferably implemented as an infinite impulse response (IIR) filter to eliminate sharp transitions in the network application data images. A random access memory is used to store the lines of the filtered images and any adjacent lines used for the filtering operation. Alternate lines of the filtered images are retrieved from the random access memory to provide an interlaced image of the filtered network application data images. The interlaced images are displayed on an interlaced display unit of a television system.
